Frauds have plagued telecommunication industries, financial institutions and other organizations for a long time. The types of frauds addressed in this paper include cellular communication frauds, credit card transaction frauds, and computer intrusions. These frauds cost the businesses millions of dollars per year. As a result, fraud detection has become an important and urgent task for these b...

In many studies of market microstructure, theoretical analysis quickly becomes intractable for all but the simplest stylized models. This thesis considers two alternative approaches, namely, the use of experiments with human subjects and simulations with intelligent agents, to address some of the limitations of theoretical modeling. The thesis aims to study the design, development and character...

Game playing has long been a central topic in artificial intelligence. Whereas early research focused on utilizing search and logic in board games, machine learning in video games is driving much of the recent research. In video games, intelligent behavior can be naturally captured through interaction with the environment, and biologically inspired techniques such as evolutionary computation, n...

In a distributed system, the task of finding relevant information and services in a timely manner is complex. When using traditional searching techniques across heterogeneous systems and multiple data formats, this task becomes nearly impossible. This paper will examine intelligent search algorithms that can be used to perform fast and reliable distributed searches. Some of the algorithms exami...

Distance learning involves a lot of work of human assistants. These assistants need to be connected for answering student doubts and questions. Intelligent agents can do part of this work. However a problem appears with this promised possibility: how to connect educational applications with these agents. This paper presents a solution to this problem, in which both the capture of student’s inte...

As computer games become more complex and consumers demand more sophisticated computer controlled opponents, game developers are required to place a greater emphasis on the artificial intelligence aspects of their games. Our experience developing intelligent air combat agents for DARPA (Laird and Jones 1998, Jones at al. 1999) has suggested a number of areas of AI research that are applicable t...

This paper describes “The Trial The Trail” a work of interactive drama for a projection-based virtual reality system. The project marries a virtual reality authoring system and an artificial intelligence system.
